PAPER-FEEDING MACHINE.

To all whom it may concern:

Be it known that I, JOHN H. BARR, a citizen of theUnited States, and a resident of Kansas City, in the'county of'Jackson, and State ofMissouri, have invented certain new and useful Improvements in Paper- F ceding Machines, of which the following is a specification.

Thisinvention relates to' paper feeding machine, and, is designed more especially for feeding slips or 'labelszfor use on mail pouches, tie sacks and the like, and my object is to produce a machinefor feedingsuch slips of .paper from a pack one at a time, in such a manner that each slip withdrawn from the pack shall be disposed a predetermined distance behind the preceding slip and thus avoid any chance of the fed slips overlapping.

With this general object in view the invention consists in certain novel and peculiar features of construction and organization of parts as hereinafter described and claimed, and in order that the same may be fully understood reference is to be had to the accompanying drawing, in which:

Figure 1, is a fragmentary front view of a paper feeding machine embodying my invention.

Fig. 2, is a section taken on the line II-II of Fig. 1.

Fig. 3, is a fragmentary top view of the machine with the paper holder broken away.

In the said drawing, 1 is a base provided with side standards 2, one of which is pro vided with a vertical series of teeth 3.

4 is a transverse shaft journaled in the side standards and equipped with a feed roller 5. Vertically below shaft 4 is a second shaft 6 journaled in said side standards and equipped with a feed roller 7 normally in frictional engagement with feed roller 5, said rollers being preferably of rubber or other compressible material so that they shall be capable of feeding slips of paper or the like betweenthem, and rotatable with and located at the ends of feed roller 7 is a pair of cams 8 for a purpose which hereinafter appears. One of the shafts, preferably shaft 4, is adapted for rotation through any suitable means, the preferred method being by means of a manually operable handle 9.

10 is a cross rod connecting the standards 2, and mounted upon said cross rod is a rock Specification of Letters Patent.

As this occurs the uncut portions of the cams pass into engagement with the arms 14 and hence repress the same and the box to prevent the rollers from starting the feeding of the next slip of the pack as the end extremities of the one being fed by said rollers. pass out of engagement with the latter. Shortly after this occurs the said enaged slip is disposed of bv said rollers and the latter have rotated vsufliciently to again cause the cut away portions of the cams to pass the arms 14, and permit the spring 20 to readvance the box until the second slip is in engagement with the rollers. when the act on described is repeated.

To support the box at the described elevation. the rock frame is provided with a pivoted dog 21 for engagement with the proper tooth 3. the vertical adiustment of the box being determined by reference to a stationary indicator- 22 projecting upwardly and I,
